What Examples Exist Of Things We Cannot See

What examples exist of things we cannot see?

For instance, waves that are present but that we cannot see are floating all around us. Things like radio waves, wifi and bluetooth signals, cellphone signals, and more. A radio is a fantastic illustration of this. When something is said to be invisible, it means that it cannot be seen, for instance if it is transparent, hidden, or very small.For instance, waves that we can perceive exist but cannot be seen are floating all around us. Bluetooth signals, cellphone signals, and more. A radio is a great illustration of this.

What is the name of something that exists but cannot be seen?

Initially known as missing matter because astronomers were unable to detect it by looking at the universe in any region of the electromagnetic spectrum, dark matter is the name scientists have given to the particles we believe to be present in the universe but that we cannot directly see. There is, however, matter in the universe that does not emit light in any region of the electromagnetic spectrum, making it impossible for us to see it with telescopes. These types of matter are referred to as dark matter by scientists because their peculiar characteristic makes it impossible to observe them.In fact, scientists can only infer the existence of dark matter from the gravitational pull it appears to have on visible matter. About 27 percent of the universe is made up of dark matter, which appears to outnumber visible matter by a factor of about six to one.Fritz Zwicky of the California Institute of Technology first used the term dark matter in 1933 to refer to the invisible substance that must predominate in one aspect of the cosmos, the Coma Galaxy Cluster.Even though it has gravity, dark matter is unlike anything that has ever been observed by science. Dark energy and dark matter make up 95% of the universe. For all the matter and energy we are aware of, only a meager 5% is left.

Can something be both real and unreal?

No, the law of non-contradiction expressly forbids such a thing, and it states that nothing can exist and not exist at the same time. It cannot occur or exist if it is impossible.

What is the existence paradox?

The paradox is that we appear to be aware that there is an actual reality. It should be noted that the claim is not merely that there is a reality, but also that we, as creatures in this reality, are aware of it. One of mathematics’s most perplexing ideas, infinity, is where the paradox originates. Although it doesn’t act like one, infinity feels like a number. Infinity remains invariant no matter how many finite numbers are added or subtracted from it.
